I thought it was a decent book at first and I dismissed all the messiness of the plot and was intrigued to learn how the author was going to bring it all together. The twist at the end sickened me to the core. The author didn't even try to condemn Sarah as she revealed the truth. Maybe the horrific nature of her character is so bad it doesn't need to be emphasized. If anyone finds justification and understanding with her actions, you should seek help.
